Question

This question specifies that -P allows GNU grep to grep for a tab

grep -P '\t' config/file.txt

However, using git grep, I can’t work out how to grep for a tab:

git grep '\t' # Looks for files with the letter "t" instead
git grep -P '\t' # Invalid option
git grep -E '\t' # Does the same as without the -E

And there doesn’t seem to be an option for substituting in your own grep program. Is my only option to slurp the entire contents and then use GNU grep on the results?

You can work around this by typing a literal tab into your command:

# type it with ^V then tab
git grep '  '
